I was wondering how much chicken food to give your chickens a day. I just measured what I have been feeding my eleven chickens daily and it is 9 cups. They usually get oatmeal in the morning. free ranging for a few hours a few days a week. Any way my real question is with the grain. It is an organic laying ration that they are on and they are between 5 and 10 months old. Thanks I really appreciate the feed back.
